Once separated, each split lc travels though a separate fpc, and finally each set of lc are combined into a single fibre.
A set of lc are selected for a single user to receive, such that they share entanglement with all other users in the network, as shown in Figure REF  (e).
This may be performed dynamically such that the connectivity of a network may be continuously changed.
Dynamicity allows for situations where an actively switched network would improve the performance aswell as lc reassignment when network users are changed.
The light from the single fibre is then measured by a user inside of a rq.
This measurement has a passive basis choice, preformed by a beam splitter, and then overlaps one of the two measurements from each basis onto one from the other basis reducing the number of spd required at each user.
Once all users are receiving photons from the es, correlations are calculated between every pair in the network, allowing users to generate a sk through the Bennett-Brassard-Mermin qkd protocol[1]}, [2]}, commonly known as the BBM92 protocol.
